Two keys only one fob works?

Hi

Our recently purchased 75 came with 3 keys (one just for the boot lock)

Two keys work the door locks and ignition and both the little red led.

One key works remotely. The other doesn't.

Thinking the battery could be low I replaced the battery for a known good Duracell battery and still nothing. I've tried to re-sync the key in the hope it would work but not sure if I did it correctly.

I've done a search on the forum and found there to be a few different ways of syncing the key.

Could someone give a way to sync the fob? If the same key works in the door lock and starts the car, surely it's coded to the car?

Thanks in advance
Rob
